【摘要】 本文用量子力学中的密度矩阵算符理论导出了 Po　¨ schl- Teller势阱中的光整流系数的解析表达式 .考虑到在 Po　¨ schl- Teller势阱中存在两个可调参量 k和 λ,并且势阱的形状随着 k和 λ取值的不同而明显不同 ,从而其光整流系数也发生相应的变化 .因此我们可以通过调节 k和 λ的取值而获得 Po　¨ schl- Teller势阱中的光整流系数的变化规律 ,并找到其最大值 ,从而为实验提供必要的研究方向与理论依据更多还原

【Abstract】 Analytical expression of the optical rectification in the Po ¨schl Teller well is obtained by the density matrix method.Since there are two adjustable parameter k and λ in the Po ¨schl Teller well and the shape of the well is changed with k and λ,the coefficient of the optical rectification will change with the parameter k and λ too.It can be obtained the variational rule of the optical rectification coefficient by adjusting the parameter k and λ.From the rule the maximum of the optical rectification coefficient can be got.更多还原
